Dr. Conor Keegan:

I will address some of Deputy Durkan's questions, particularly his first one on updating data on a regular basis. That is a good point. It is something we have considered and that we hope to do, particularly in light of the uncertainties of these projection models in terms of where there will be population growth, changes in activity rates and so on.

We have a huge number of data agreements with both public and private providers because of the fragmented nature of the system for our base year 2015 and our activity data on which these models are predicated for 2015. Those data agreements are largely rolling and, therefore, we can update them to access more up to date data. An issue is that there will always be a lag between the availability of data and our ability to run projections. For example, by the time 2017-18 data are available and have been provided by our data providers, it could be 2021 by the time we get that 2017-18 data. There are those types of lags in place between when data become available and running our projections but as the research progresses, we hope to continually update and validate our models.
